TANK YOU DEAR georgi.g.zhelev
The relationship between the base D in Q4 with the coil is cut. This is true?

[georgi.g.zhelev]

ps-g

coil diam. 20cm : 32 turn. 2 x 0.51 R= 1.2 ohm !!!
mesyna,good luck!!

Hi,MESYNA!! very well !! I help you. You build PS-G or PS-G light ???
Please schematic.

Good Luck!

tank you my friend

Hello to all friends


I built pulse star bg.

The launch of this circuit was difficult. Normally without any voice coil circuit is slightly wet fingers, but when I Asylatvr transistors 555 and alarm system to Mykshm.

When the coil 20 cm can be connected to the metal detector q4 is extremely hot and burns. Profile coils is this way: 32 round wire diameter of 0.50 to 20 cm.

I'll guess that the problem is the coil.

Metal detectors instead of the 2n2646 transistor ujt I use. I want to know that this device provides a problem? Base sequence in this transistor pcb do not know Please help me.

Tl072 use instead of my 1458. This problem does not and I do I replace them?

Please help me solve this problem, please

With respect

mesyna

Hi kt315,
Thanks...
Did you build this device?
which is latest PCB and schematic of pulse star...


anyone build this device... please guide us to building it...
